New paper out in @pnas.org led by Marine Cazenave shows different locomotor repertoires in Swartkrans Paranthropus and Sterkfontein Australopithecus! www.mpg.de/26471037/swa...
Swartkrans Paranthropus and Sterkfontein Australopithecus had different locomotor repertoires
Paranthropus robustus from southern Africa combined upright walking and more frequent climbing than the older Australopithecus in the same region

Out today in @pnasnexus.org! We present evidence for a new way to characterize the vestibular organs, challenging traditional assumptions about how the human inner ear is organized.🧵 1/5 academic.oup.com/pnasnexus/ar...
Evolutionary modularity of the primate vestibular system: Morphological distinction of otolithic and canalicular organs
Abstract. The mammalian inner ear is traditionally divided into two systems: the peripheral vestibular system (for balance) and the cochlea (for hearing).

🚨Science news! Recent research led by Meghan Forcellati, a comparative biology Ph.D. student in the Museum’s Richard Gilder Graduate School, has uncovered new clues about reptile evolution by studying the bony encasements of the inner ears of living lizards and snakes.
Bony Inner Ears Offer Clues to Lizard Evolution | AMNH
Scientists hoping to reconstruct how extinct lizards and snakes lived have turned their attention to the inner ear.

📢 Call for Papers! We invite submissions for special issue “Development, Evolution, and Comparative Anatomy of the Larynx.” This issue aims to highlight interdisciplinary work exploring the development, evolution, and structure–function relationships of the larynx across species. 📅 Deadline: Sep 15
I'm happy to present our paper in which we describe hominin postcrania from Drimolen. Many of these specimens sat in a drawer at Wits Uni for > 20 years. It's amusing to me that the image here includes two fossils in that drawer that were labeled "hominin" but that we decided are not! 1/

I am really excited to share news of this new jaw...until now Paranthropus had been conspicuously absent from the Afar. Fieldwork at Mille-Logya is not easy, and this fossil is the result of years of very hard work (and a lot of days of dry screening by our team)! www.nature.com/articles/s41...

This is great. It's not as in depth as the suggestions here, but at my JC in grad school we always asked two questions at the end: "What is the most valuable thing we can take from this paper?" and "What's the next step we would take related to that most valuable thing?" It was fantastic.
It's easier to tear down than build up, and in science we have a bad case of that. So: how to lead a journal club that actually finds value in what you read. scientistseessquirre... 🧪
Just finished this awesome new-ish book by @nicolasmathevon.bsky.social on animal communication. It covers a lot of ground with a huge diversity of species—& it's a blast to read! Great for those interested in sensory ecology. (I had skulls of all the cover animals, so I snapped a photo! 😃)
Today's bombshell in @nature.com by Lindsay Zanno & James Napoli @jgn-paleo.bsky.social (bit.ly/4qBE6ng) shows that putative juvvy T. rex fossils actually are Nanotyrannus. I reviewed the manuscript, so Nature invited me to write the News & Views commentary. Free link: rdcu.be/eNv94 🦖
New craniodentally associated P. boisei post crania! ✋ 🦶 from Koobi Fora 🔥 Congrats to carriemongle.bsky.social caleyorr.bsky.social et al!
Paranthropus boisei is a human fossil cousin w/ giant jaws and teeth that lived in East Africa ~2.6 to 1.3 million years ago. Whether it could make & use tools has been a paleoanthropological mystery since the 1960s. Our new paper describes the first firmly associated hand and foot. 1/

New paper from my lab & Drimolen team (@ozarchaeomaglab.bsky.social) on the DNH 43 hominin pelvis. I first saw it in 2019. Given the importance of the pelvis in the evolution of human locomotion and birth, I was surprised only a basic description had been published. 1/ #paleoanthropology 🏺🧪
